Germination and growth of Bacillus cereus spores from emetic and diarrheal strains were measured in Trypticase soy broth (TSB) and in autoclaved rice/beef extract from 5°– 55°C. Growth for some strains occurred from 15°– 50°C, and little difference was noted between responses of diarrheal and emetic types or between media, except a higher maximum population was achieved in rice. Germination was more extensive in rice than in TSB at <15°C and was generally more extensive for diarrheal strains in either medium.
